Bitcoin one more leg down before takeoff?

Getting ready for one last push down in the A-B-C (blue) correction wave for BTC before price action will take off again. BTC has been consolidating on low volume over the last two weeks, on the lower end of its trend channel (yellow), creating what looks like a pennant flag (red). This signals further downside is imminent.
However, overall sentiment is still extremely bullish and key support around $ 8500, coincides with the 78% Fib. Retracement level as well as previous consolidation from the beginning of December.
Looking to place buy orders at around $ 8900 as buyers have previously stepped in somewhat “early” during correction/ consolidation phases, and I am still bullish on BTC for the medium and long term. If $ 8500 does not hold then I believe we have to say goodbye to 100K BTC 2018.
